RELATIONSHIP TO TI{E COMPBEFIENSIVE PLAN According to the Garfield County Comp Plan of 1984, this site lies in "District A: Urban Area of Influence". Urban areas of influence are described as having the best ability to absorb growth. Only areas with minor or moderate environmental constraints to development, which surround a municipality, are included in this district. The recommended density is no greater than seven (7) dwelling units per acre, or a density which is compatible with the surroundings. II. PROJECT INFORMATION A. SiIe Description: The property is located south of the Cactus Valley Ditch, at the Page I of St* B. intersection of ukele Lane and Highway 6124. There is very liule topographic change across the site. It generally drains from the north to the southwest. It is currently used to grue livestock and is also occupied by two (2) existing dwelling units and an outbuilding. The existing residences are served via a paved driveway from Hwy 6124. Yegetation consists of grass and a few cottonwood trees, Develop,me{rt Proposal: The plan is to divide the roughly twenty-five (25) acres into nine (9) residential lots with eleven (11) dwelling umts (a guest house and an accessory dwelling unit are proposed on lots 4 and 6). All building will occur within building envelopes, which range in size from ll2to l-ll3 acres. The proposed density is I dwelling unit per 2-ll4 aores. Adjacent Land Uses: Agricultural and residential land uses are adjacent to the site. C. m.REMEW AGENCY AND OTHER COMMENTS: Referrals were sent to the following: A.

Subdivision: Single family dwellings are a use by right in the AIRIRD zone district. The lot design generally meets the standards set forth in the SuMivision Regulations. Pursuant to section 3.02.01 of the ZoningResolution, an accessory dwelling unit may be approved as part of a subdivision. However, a guest house may only be approved as a special use under the special use permitting process, and can not be approved as part of this suMivision application process. B. Garfield Countv Comprehensive Plan: The application appears to be in general conformance with the comp plan. C. Town of Silt Comprehensive_ Plar/Comments: See memo dated 3/3100. The Town has requested the following conditions be placed on any approval of the application: residential units to provide a buffer from adjoining areas. allowed and a requirement for use of kennels. surrounding agricultural uses and minimization of conflicts. the traffic impacts on the I-70 Silt interchange through coordination with the town and other developers, D. ADU/Guest Housg: As discussed previously, the regulations do not allow a guest house to be approved by a subdivision process. The applicant must acquire guest house approval via a special use permit process. The proposed accessory dwelling unit on lot 6 must meet the following standards (5.03.21of the Zoning Res.): Page 3 of 6l'l L. (l) The minimum lot size shall be four (4) acres containing a building site with slopes less than 40% at least two (2) acres in size, Q) fhe gross floor area for residential use occupancy shall not exceed 1500 sq. ft.(3) Approval from the subdivision homeowners association and/or allowed by covenant if appl icab le. (4) Proof of a legally adequate source of waterfor an additional dwelling unit. (5) Compliance with the County individual sewoge disposal system regulations or proof of a legal ability to connect to an approved central sewage treatmentfacitity. (6) Only leasehold interests in the dwelling units is allowed. (7) That all construction complies with the appropriate County building code requirements. (A. 9 5 -07 6) The building envelope shown on Lot 6 is approximately 1-113 acres. It will need to be increased on the final plat to 2 acres. The proposed covenants (sect. 3. l) currently prohibit more than one (l) single family dwelling and will need to be amended. The covenants should also reflect that the accessory dwelling unit may not exceed 1,500 sq. ft. and may not be sold as a separate interest. GeotechnicallRadiation Information: In a letter dated ll3ll}},Hepworth-Pawlak Geotechnical, lnc. notes that the site is not in a geologic setting that would indicate high concentrations of radioactive materials in the natural soils and underlying rock formation. There is the potential presence of radon gas and testing could be done when the residences have been completed. F{P (iob #199731 lllrl/99) states that it should be feasible to develop the property as proposed on the site, provided good engineering principles and practices are used in the design. I{P notes the importance of providing consultation during design and construction to monitor the implementation of their geotechnical recommendations. Site specific studies should be conducted for individual lot development. The geologic conditions which shoutd be considered as planning and design proceeds are: FoundatioJ.r Conditions: Some areas may have collapse or settlement potential. Typical mitigation includes control of landscape irrigation, reinforced foundation walls, and low footing bearing pressures. Basements may need to be limited or avoided due to shallow groundwater conditions. Flooding & Surface Drainage: Due to the natural slopes, some flooding potential should be expected. The irrigation ditch to the north may need to be lined. Earthquake considerations: Residences should be designed to withstand moderately strong ground shaking as the area is in seismic Risk Zone L celia Greenman, of the colorado Geological Survey, states the site can be successfully developed if close attention is paid to surface drainage, which is critical to managing problem soils. Structures should have positive drainage, downspouts should discharge at least 6' from tre houses, xeriscape (water Page 4 ot fill F. conserving) landscape conoepts should be used, and each lot should have an identified backup site for a leach field (leach fields should not be used as animal containment areas or for auxillary building sites). These recommendations should be followed and staffsuggests the covenants be amended to reflect the use of xeriscaping methods. Wright Water Engineers (WWE) notes that due to the potential for settlement, differential movement, and groundwater conditions on the project, site-specific geotechnical studies should be conducted for proper foundation design. This should be reflected in Section 22 of the covenants and on the plat. Access/Traffic/Road Maintenance: Esther Court, the new proposed access, will provide access to six (6) of the lots (lots 1,2,3,7,8,&9) from County Road229 (Ukele Ln.). The proposed fiffy (50) foot wide right of way will terminate in a fifty (50) foot cul-de-sac, with a total length of about six hundred (600) feet. Access to the remaining three (3) lots (or five dwelling units) is from the existing access drive from Highway 6124. The application proposes a forty (40) foot wide, four hundred fifty (450) foot long right-of-way (note: the plat shows an easement, the written application mentions a r-o-w, it must be a r-o-w ) consisting of a sixteen (16) foot wide paved surface. A twenty-five (25) foot wide emergency access easement, containing a twelve (12) foot wide gravel road, connects the two dead ends. The applicant has attempted to eliminate a shortcut toHwy.6l24by not providing a'lhrough road". All roads within the subdivision, except the emergency, tank, and well access, will be chip sealed. The roadways will be dedicated to the public but will be privately maintained by the Homeowners' Association. The application includes an unsigned highway access permit (CDOT permit #399152) which allows for 300 ADT. Per the comments of the Road & Bridge Department, the applicant has agreed to dedicate an additional fifteen (15) foot right-of-way along the county road for the entire length of the development, to install all traffic control devices per code, not to place fencing in the right of way, to pay the applicable road impact fees, and to obtain an access permit from the R&B department. The application appears to generally conform to sections 9:35 (road standards), 9:33 (dead end streets), and 9:34 (dedication to the public) except as follows: permit. of way and must be named on the final plat as well as slightly reconfigured so that the 37' radius becomes a 50' radius. Fire Protection: The site is located in the Burning Mountain Fire Protection District (BMFPD) with ambulance services provided by Silt. The application G. Page5 af Wl'( H. states that the potable water system will provide the required fire flow for the subdivision. Don zordel,the Fire Chiet indicated to the applicant that 10,000 gallons is necessary for fire protection. The tank has been sized to accommodate the 10,000 gallons in addition to 350 gpd/unit storage for the homes. The water supply is from an existing well located on lot 4. A 20,000 gallon partially buried (approx. 2' of tanks are exposed) concrete water storage tank will be located on the northwest corner of lot 7. A series of pumps will transport the water from the well to the tank. The application funher states, "Please note that the BMFPD adopts the UFC as reference only... The UFC would require a minimum of 180,000 gallons storage for this tank for the fire flow conditions... The service demands from the subdivision would not be capable of using the volume of water to keep the water in the tank from becoming stagnant... [which would require] additional maintenance facilities." 7 rifien confirmation from the Fire District that the proposed development has adequate water and facilities must be provided as part of the preliminary plan. WWE notes ttrat the letter should specifically contain approval of the 10,000-gallon !s-re"q"g*. water: The application states the water supply will be from an existing well located on lot 4. A copy of the approved well permit was included in the application (#53426-F). The well will operate under wDwcD (west Divide Water Conservancy District) contract #950815JS(a). Resource Engineering found no evidence of any wells within 600 feet of the subject well. water will be transported to the water storage tank on lot 7 by a series of pumps. The community water system will be built at the applicants' expense but will be owned and maintained, to the property line, by the HOA, as specified in the covenants. A24 hr. well test reveals that the well is capable of physically producing over six (6) times the daily in-house demand for the subdivision. Water samples indicate the limits for sodium, yg!fa15:, dissolved, solilb and hardness areS.ce$gg. The propose.i water trea.tment is chlorinaffi as discussed in SGM's letter dated 2122100. The chlorine injection, along with the contact time, will resolve the non-coliform bacteria problem. Although the water would be safe for drinking the water would still be'ohard". SGM encourages individual homeowners to determine further treatment as they desire through the use of water softeners and/or reverse osmosis systems. The State Engineer finds the proposed water supply will not cause material injury and is adequate (see letter dated 3121100, page _). The approved well permit will limit the use of the well to household purposes inside l1 single family dwellings, the irrigation of 1.5 acres of lawns/gardens (approx. 6,000 sq.ft.per dwelling), and the watering of domestic animals.

We recommend that this section provide initial rules and regulations for use and operation of the irrigation system, substitute water supply plan. A water court approved augmentation plan will ultimately be required for the well. The Applicant should include this cost in the SuMivision Improvements Agreement or indicate in Section 20.1 of the covenants that the lot owners are responsible for this cost with the WDWCD when it arises. potable water systern is not designed for outside irrigation and the covenarfs strould prOhibitSuChUSeSinSeCtiOn20.l and20.2.rN br)Irrt ps $-rr'.. >r'.;1 ett 1::yt2'rn't-, grueous chlorine for a small HOA system. should be included in Section 20.1 of the covenants. InigationlDitcheslEasements: The plan reflects a twenty-five (25) foot wide ditch easement for the Cactus Valley ditch. The building envelopes have been set back thirty (30) feet from the easement, as requested at the sketch plan public meeting. The applicants hold a reliable water right of senior priority in the Cactus Valley ditch which entitles them to 3.75 shares, or 0.53 cfs, of irrigation water. A central, independent gravity flow raw water inigation system is proposed to service each lot. A 5,400 gallon buried water storage tank will be located on the northeast comer of lot 6. The HOA will own and maintain the inigation system to each property line. The individual low owner will be responsible for providing and maintaining their own booster pump. The wananty deed for the properfy (8870,P727) describes an access easement across the northwest corner of the property for the use of the Dunbars, and their heirs and assigns, to maintain their adjudicated springs and their headgate from the Cactus Valley Ditch. The applicant has noted no legal description of the easement currently exists. The applicant must locate the easement on the final plat and create/include a legal description of said easement on the final plat. PageT ot fi t4 J. WWE also notes the following (letter dated 3/30/00): DitchCompany wittra format EasementAgreemantorotlrerwise accepted in udting by the ditch company, whichever may be the appropriate legal course of action. project Waste.water: The applicant has investigated the possibility of connecting to the Town of Silt's wastewater services and determined it is infeasible for two (2) reasons: r 1) The nearest rnainline is approx.fone (l) mile away and connection would be too costly. 2) The grade differential would require a lift station to force the flow back to town- For these reasons, each lot will be serviced by an engineered Individual Sewage Disposal System (ISDS). Although a high groundwater condition exists and the soils are slow to percolate, SGM has stated confidence in engineered ISDS given the two plus (2+) acre lot sizes. An Evapotranspiration Absorption system (ET), which may require considerable area to place, will likely be needed. The application states that operation and maintenance of the ISDS will be the responsibility of individual lot owners. It states that those responsibilities are contained within the covenants and maintenanca guidelines will be distributed to each lot owner at closing. WWE strongly discourages the use of ET systems for this project. In addition, WWE states that an ISDS management plan should be included in Section 7 ofthe covenants. Plan components typically include special design considerations/criteria, inspection schedule, and a homeo\Mlers guide to maintaining an ISDS system. A good source for this information is "Maintaining Your Septic System-A Guide for Homeowners" in Pipeline, Fall 1995, Vol.6, No.4 sponsored by the EPA. Staff suggests this brochure be provided to all homeowners (and can provide this information to the applicant upon request). Drainage: There are no major drainageways located on the properly. The application states storm water drainage will be collected by means of borrow ditches and culverts and transported to four (4) different detention ponds located on the southwest corners of lots 3,4,5,&6. The pond on lot 3 will serve to capture the increased flow rates on lots 1,2,&3 and7,8,&9. Lots 4,5,&6 will require individual ponds to service each lot.

WildlifeA/egetation: The application includes a DOW WRIS wildlife habitat checklist. It indicates that the following are entirely in the area;I eatd Eagle Winter Range I Mule Deer Winter Range I Uute Deer Overall Range I trrtute Deer Resident Population The applicant contacted Don Crane, of the DOW, regarding the project. He was most concerned with conflicts between dogs and wildlife and maintaining low fencing. In his review letter dated 3ll3l00 Don Crane states he is quite familiar with the site and is satisfied that his stated concerns have been sufficiently addressed in the covenants. The DOW can find no significant impact to wildlife if the protective covenants are approved and enforced in their present form. Existing vegetation consists of irrigated pasture grasses, irrigated blue grass lawns, and cottonwood trees. The existing trees will be protected through the development of the prqect. Steve Anthony, of GarCo Vegetation Management, has stated that the revegetation plan is acceptable (the plan is contained on pg.4 of Taufer's 2l2ll00letter). He has requested the covenants be amended as follows:t Include language that reminds landowners that it is their responsibility, according to the Colorado Noxious Weed Act, to manage any County Noxious Weeds that are on their property (he suggests this go in the "maintenance of property" section). I Management of noxious weeds on roadways, drainage ditches, and common areas should be addressed. Responsibility for this should be designated. WWE notes the following (letter dated 3/30/00): Page 9 of t&.tl discuss/analyze the impacts, if any, from the project Field observations indicate that wetlands may exist in the southem and western areas ofthe property. M. Fees: As determined by Section 9:80 of the Subdivision Regulations, the applicant will be required to pay $200 per each new parcel (8 new lots X $200 = $1,600.00) for School District fees in lieu of land dedication. The property appears to lie in uea6 of the Capital Improvements plan. The road impact fees are approximately $2,100 per dwelling unit that impacts a county road (6 units), less the appropriate discounts. In the event any fees increase before the time of final plat, the increased fees shall be paid. Any applicable fire district fees will be due prior to final approval of the final plat. The applicant should be aware that property taxes will increase following the change from agricultural valuation. N. Covenants: The covenants should be amended as discussed elsewhere in this report and as follows: downward and towards the interior of the subdivision". O. Other Utilities: All utilities must be buried. Propane tanks will be screened from view. Electric and telephone: Public Service Natural Gas: not available. Propane gas will be utilized.

One (1) new solid-fuel buming stove as defined by C,R.S. 25-7401, et. sew., and the regulations promulgated thereunder, will be allowed in any dwelling unit. All dwelling units will be allowed an unrestricted number of natural gas burning stoves and appliances. 4) All exterior lighting will be the minimum amount necessary and all exterior lighting will be directed inward, towards the interior of the subdivision, except that provisions may be made to allow for safety lighting that goes beyond the property boundaries. 5) No further divisions of land within the Subdivision will be allowed. 6) Site specific geologic studies must be performed on individual building envelopes to determine design level recommendations. 7) Radon gas may be present and should be tested for once building construction is completed. 8) Lot 6 shall be permiued one (l) accessory dwelling unit provided it meets the conditions of section 5.03.21of the Garfield County ZonngResolution of 1978, as amended. 9) Homeowrers should consider firther treatment such as water softeners or reverse Page 13 ot $qft 16. osmosis to eliminate problems associated with hard water. l0) Colorado is a "Right-to-Farm" State pursuant to C.R.S. 35-3-101, et seq. Landowners, residents and visitors must be prepared to accept the activities, sights, sounds and smells of Garfield County's agricultural operations as a normal and necessary aspect of living in a County with a strong rural character and a healthy ranching sector. All must be prepared to encounter noises, odor, lights, mud, dust, smoke chemicals, machinery on public roads, livestock on public roads, storage and disposal of manure, and the application by spraying or otherwise of chemical fertilizers, soil amendments, herbicides, and pesticides, any one or more of which may naturally occur as a part of a legal and non- negligent agricultural operations. l1) All owners of land, whether ranch or residence, have obligations under State law and County regulations with regard to the maintenance of fences and irrigation ditches, controlling weeds, keeping livestock and pets under control, using property in accordance with zoning, and other aspects of using and maintaining property. Residents and landowners are encouraged to learn about these rights and responsibilities and act as good neighbors and citizens of the County. A good introductory source for such information is "A Guide to Rural Living & Small Scale Agriculture" put out by the Colorado State University Extension Office in Garfield County. fnf -@lQ o.r W>>q',5 r-',u- ffuffi';,wy ^ftu) ^^.-^o T 'oa1s >l,u W V>sa1sasn Page 14 of Ml4 GARFIELD COUNTY PROJECT REFERRAL MEMORANDUM TOI KIT LYON. GARFIELD COUNTY PLANNER FROM: DAVIS FARRAR - SILT PLANNER SUBJECT: COMMENTS ON T}M UKLE ACRES SUBDIVISION PRELIMINARY PLAT REFERRAL DATE: 03/30/00 CC: CRAIG OLSON - SILT TOWN ADMINISTRATOR Thank you for the opportunity to review the llkele Acres Preliminary Plan subdivision application. This project lies within the urban growth boundary shown on the Silt Comprehensive Plan Land Use Map and within the three-mile planning area around the town. The application states that the request is for a total of 9 single-family residential lots plus a caretaker unit and a guesthouse for a total of I I residential structures on 24.98 acres. The Silt comprehensive plan identifies this area as Agricultural Conservation PUD. Under this land use classification, the comprehensive plan anticipates and proposes clustering of residential lots for purposes of preserving agricultural lands and agricultural functions. The proposed development design includes no clustering of lots or structures. In the comprehensive plan under this section "land use general policies" the plan states, "suburban sprawl will be avoided. The subdivision of rural agricultural areas outside the designated urban $owth areas for the purpose of creating low density residential development on large lots of two, ten or 35 acres will have undesired effects including: changing the rural character of the area into one of suburban sprawl; making it diflicult for adjacent agricultural uses to operate; placing residents in remote areas where urban services for road maintenance, transportation, recreation, police and emergency services, water and sewer, human services in schools are inefficient and expensive to provide." The plan goes on to state, "low density sprawl development unnecessarily burdens municipal and County financial resources often resulting in increased taxes in which urban areas subsidize low density developments." Garfield County passed a "right to farm" resolution several years ago for purposes supporting continued agricultural operations in the County. Subdivision of rural areas into two-acre gnd style developments will add to the adverse pressures on agricultural operations in the form of dogs at large, trespass, complaints about chemical applications and similar objections from residential dwellers. 5 Recently, the Silt Area Economic Development Council identified preservation of agricultural functions in the Silt area as an important goal. Their intent is not to eliminate residential subdivision activity but rather work to make it compatible with surrounding agricultural functions. This can be achieved through clustering of lots, strict dog controls, education of new residents about agricultural operations and similartechniques. The proposed development does not include any mechanisms that further the objectives of the S. A. E. D. C., Silt Comprehensive Plan or the Garfield County "Right to Farm" resolution. The I 70 interchange located in Silt is impacted by ever increasing traffic volumes from Silt and the surrounding areas. In an effort to address the traffic impacts to this interchange, the town is conditioning development approvals with a requirement to evaluate the traffic impacts created by individual projects on that interchange. Most recently, the town has proposed that the developers of Stillwater Ranch, Ferguson Crossing and Spruce Meadows participate in a comprehensive study of traffic impacts to the interchange zrrea. Individual developer participation is to be based upon the proportionate impacts created by each project on traflic volumes. The town recommends that the developers of the Ukele Acres Subdivision also participate in this analysis based upon the developments proportionate share of generated traffic. Using an accepted single-family residential traffic generation figure of 9.55 single trips per day per dwelling unit, the project will generate approximately 106 vehicle trips per day. The developers should be required to contribute a proportionate share of the total cost of such a study based upon this trip generation figure. Without a proportionate contribution from this project, these additional vehicle trips will impact the interchange without due compensation. The net result will be that existing taxpayers will be required to pick up the cost of this impact. The proposed preliminary plan shows a single culde-sac offof Ukele Lane. A secondary 25 ft. "emergency access, utility and drainage easement" is shown providing access to the lots in the west end of the subdivision. A more effective access configuration would be a loop streetthrough the development from Ukele Lane to Highway 6 &24. This configuration would provide better access to the proJect, dual access for emergency purposes and better access for road maintenance. Project drainage must be designed to avoid any increase in historic runofffrom the site. Silt lies at the mouth of four separate drainages. The headwaters of these drainages all lie outside of the municipal boundaries of the town. Any increase over historic runoff rates will adversely impact drainage control structures designed and installed in town. All drainage calculations for projects that impact these watercourses must consider the design characteristics of the lower basin drainage structures. Redesign and reconstruction of the existing facilities is a very expensive proposition. Any redesign or reconstruction necessitated by adverse runoffcharacteristics in the upper basins will cause an undue hardship for existing taxpayers. tb ln summary, it is requested that the Garfield County planning commission and county commissioners consider the following conditions as they review the Ukele Acres Subdivision. and residential units to provide a buffer from adjoining areas. allowed and a requirement for use of kennels should be considered. regarding surrounding agricultural uses and methods of minimizing conflicts. towards a comprehensive study of the traffic impacts on the Silt I70 interchange. This could be accomplished through coordination with the town and other developers. connects Ukele Lane with Highway 6 &.24. would adversely impact existing drainage courses off-site.

A Preliminary Geotechnical Study prepared by Hepworth-Pawlak Geotech (November 1999) was included in the referral. 1) Soil. The soil is composed of alluvial fan deposits derived from Wasatch parent material. The blow counts at different horizons in a number of borings indicated low strength materials. The swell-consolidation tests show some tendency for consolidation after wetting. H-P Geotech recommends footings sized for a low bearing pressure, which is appropriate for such soils. The size of the community water tank is not stated. This will be a heavily loaded structure, and the load will vary. Foundation designs for the tank should be carefully engineered, so that settlement (and subsequent damage) does not result. A mat foundation should be considered. It is absolutely necessary that drainage be controlled at the site, as the soils are likely to consolidate after wetting, and may cause structural damage. Slopes should grade away from houses, and xeriscaping should be implemented for ground cover. Roof downspouts should discharge at least 6 ft from the houses. 2) Septic systems. Each lot should have a backup site for a leach field, whether the field is conventional absorption or engineered. The leach field sites should be removed from auxiliary construction (sheds) and animal containment areas. In summary, the site can be successfully developed with close attention to surface drainage, which is critical in managing problem soils. Please call me if there are any questions.

State Engineer Re:Ukele Acres Subdivision - Preliminary Plan SW %Section 4 & NW %Section 9, TO S, R 92 W, 6TH PM Water Division 5, Water District 39 Dear Ms. Lyon: We have reviewed the above referenced proposal to subdivide a 24.981 acre parcel into nine (9) residential lots, with a total of 11 residential dwellings to be served by a centralwell. This proposal is a modiflcation of a previous submittal for the Smith Subdivision (our letter of April 16, 1999 is attached). Total in-house water use for the 11 dwellings is estimated at 350 gallons per day or approximately 4.3 acre-feet per year. The applicant has obtained contract #95081SJS(a) for 11 acre-feet of water from the West Divide Water Conservancy District (District), and permit no. 53426-F was issued on March 20,2000 pursuant to this water allotment contract and the District's temporary substitute supply plan. Permit no. 53426-F limits use of the well to household purposes inside 11 single-family dwellings, the irrigation of 1.5 acres of lawns and gardens (approximately 6,000 square feet per dwelling), and the watering of domestic animals. Although irrigation is allowed by permit no. 53426-F, water for irrigation on each lot is to be provided by the applicant's surface water rights consisting of 3.75 shares in the Grand River Ditch Company's Lower Cactus Valley Ditch. A report from Paul Bussone, P.E, of Resource Engineering, lnc., indicates the well was test pumped on June 22, 1999 at a rate of 16.6 galions per minute for 24 hours. The static water level was measured at 43.5 feet, and the maximum drawdown was approximately 3.6 feet below this level. Based on this test, Mr. Bussone concluded that this well could provide an adequate physical water supply for the in-house uses associated with 11 single-family dwellings. The source of the proposed water supply would be tributary to the Colorado River. Due to the fact that the Colorado River is overappropriated, a plan for augmentation is required to offset depletions caused by the development. However, since this development is within area A of the District's temporary substitute supply plan, this office has issued permit no. 53426-F. Note that supply plans are temporary by definition, and that to provide for a permanent water supply, permit no. 53426-F must ultimately be included in a water court approved plan for augmentation. a-? Kit Lyon Ukele Acres March 21,2000 Pursuant to Section 30-28-136(1XhXl), C.R.S., it is our opinion that the proposed water supply will not cause injury to decreed water rights, and based on a sustained yield in the above reported range, and with appropriate storage capacity, the use of the proposed welt should be adequate for a potable wgler supply. lf you or the applicant has any questions concerning this matter, please contact Jeff Deatherage of this office for assistance.

Districts 39 & 45 Dear Mr. Barbee: We have reviewed the above referenced proposal to subdivide a parcel of approximately 24.6 acres into 9 lots, ranging 'from 2.21o 4.2 acres each, with one single family dwelling on each lot. The applicant proposes to provide water through a central water system, utilizing the well with Permit No. 46427-F pursuant to contract No. 95081sJS(a) with the West Divide Water Conservancy District (the District). A copy of the contract was not provided. Sewage disposal will be through individual septic systems. Although well permits for the intended this use may be available if the well is included in the District's temporary substitute supply plan, the existing well permit and contract do not allow the intended use, no new well permit application has been submitted for review by this office, and there is no guarantee that a well permit can be issued. Furthermore, to be considered a legally reliable source of water the well should be included in a court approved augmentation plan, since there is no guarantee that a temporary substitute supply plan will be renewed. No information was provided on the adequacy of the water supply. Based on the above, it is our opinion, pursuant to Section 30-28-136(1)(hXl), that the proposed water supply will cause material injury to decreed water rights. Due to insufficient information we cannot comment on the physical adequacy of the water supply. lf you or the applicant has any questions concerning this matter, please contact Craig Lis of this office for assistance.

(WWE) has reviewed the Preliminary Plan submittal for the Ukele Acres Subdivision near Silt. Our comments on technical issues are presented below. WATER ST]PPLY A microscopic particulate analysis test should be conducted for the well water supply due to the presence of non-coliform bacteria and the relatively shallow well construction. Section 20.1 of the covenants should reference the West Divide Water Conservancy Distict (WDWCD) water allotment contract. The results of the water quality and the need for individual water treatment facilities should also be included in this section. Reference to the WDWCD allotment contact and 6,000 square-feet of inigation should be removed from Section 20.2. We recommend that this section provide initial rules and regulations for use and operation of the irrigation system. The well permit issued for the project (53426-F) is based on the WDWCD's substitute water supply plan. A water court approved augmentation plan will ultimately be required for the well. The Applicant should include this cost in the Subdivision Improvements Agreement or indicate in Section 20.1 of the covenants that the lot owners are responsible for this cost with the WDWCD when it arises. WATER SYSTEM Although the well permit allows for outside irrigation (6,000 square-feet per lot), the potable water system is not designed for outside inigation and the covenants should prohibit such uses in Section 20.1 and20.2. The disinfection treatnent system should consider use of liquid chlorine rather than gaseous chlorine for a small HOA system. t. 2. J. 4. 5. 6.

A letter should be obtained from the Buming Mountain Fire Protection District regarding the 10,000-gallon fire storage requirement. 8. We recommend the well water quality be tested for nitrates on an annual basis. This should be noted in Section 20.1 ofthe covenants. WASTEWATER 9. The use of evapotranspiration (ET) systems for this project is strongly discouraged. 10. An ISDS management plan should be included in Section 7 of the covenants. Plan components typically include special design considerations/criteria, inspection schedule, and a homeowners guide to maintaining an ISDS system. DRAINAGE ll.The existing drainage system should be shown (e.g., culverts across Highway 6) and it should be demonstrated how the proposed system fits in with the existing systems. 12. A typical detail for the detention ponds and outlets should be shown. 13. The submittal does not indicate if the Applicant or the future lot owners will construct the "individual" detention ponds. A drainage easement should be shown on the Plat for these ponds. If constructed by lot owners, then the engineering criteria for the pond to comply with County regulations and the Master Drainage Plan for the project must be indicated on the Plat. A Colorado registered professional engineer must design the ponds. 14. The covenants should indicate that the HOA and/or individual lot owners are responsible for maintaining a functional detention basin(s). SOILS/GEOLOGY 15. Due to the potential for settlement, differential movement, and groundwater conditions on the project, site-specific geotechnical studies should be conducted for proper foundation design. This should be reflected in Section 22 of the covenants and on the Plat. WETLANDS 16. The submittal should address the presence/absence of wetland areas and discuss/analyzsthe impacts, if any, from the project. Field observations indicate that wetlands may exist in the southem and western areas ofthe property. E:\Work\WWE\92 I -047.
